Abstract:
Seeds from Paeonia ostii and Paeonia rockii have been recently identified as novel resources of a-linolenic
acid (ALA) in China. To assess whether tree peony cultivars can be used as oil
resource, fatty acids (FAs) in 60 cultivars were monitored and evaluated in
this study. The results indicated that the composition and content of FAs
varied dramatically among different cultivars, in which ALA, linoleic acid,
oleic acid, palmitic acid, and stearic acid were the dominant. The 60 cultivars
were classified into six clusters by hierarchical cluster analysis, and they
were quite distinct from each other. Finally, six cultivars with high yield and
high quality were screened out, comprising of ‘Liuliguanzhu’, ‘Hongguanyupei’, ‘LSS-2’,
‘LSS- 1’, ‘Jingshenhuanfa’ and ‘LSS-11’. These cultivars were appropriately
applied in practical oil production. Overall, tree peony oil with abundant
unsaturated fatty acids especially ALA was proved to be a top-grade source for
edible oil and nutritional supplements.
